Mahjong solitaire is originally based off of the Chinese poker game simply called Mahjong. The goal of Mahjong Solitaire is to remove every piece off of the bored by making matches, there are rules however. You cannot select a piece until it has its left or right side completely exposed and has nothing on top of it. Once you select a piece you must then pair it with another piece using the same rule. That will cause both pieces to be removed. This is a game about spotting the correct tiles quickly, and working your way through them as well as possible.
